Gear Review- Black Diamond Alpine Softshell Pants

I’ve been wearing the Black Diamond Alpine Softshell pants almost daily for the last 5 months and have been really happy with their performance. A true three season pant I’ve worn them on sunny low 70’s days rock climbing on Whitehorse Ledge, blustery Mount Washington ascents (including my two hour car to car of Pinnacle), late season ice climbing, and summer alpine climbing in the Cascades. These were the only pant I wore for successful summits of Mount Shuksan, Forbidden Peak, and Mount Rainier. All told they have seen over 200 miles of hiking and 30,000 feet of climbing and still look and perform great! Let’s take a look at why these are suitable for such a wide variety of adventures!

Comfort- Temperature Range

Probably the best feature of these pants is how they have a very large range of temperature comfort. This is primarily achieved by Black Diamond’s proprietary four-way stretch fabric (88% nylon, 12% elastane) with a DWR finish. The material is soft enough on the inside that it feels great on bare legs and so breath-able that I could wear them on high humidity warm days during bug season without any discomfort. I actually found myself not climbing in shorts this season because I liked the added protection of a full pant like this pretty much every time I headed into the woods. Despite being so comfortable in warm and humid conditions the DWR treatment and weight of the material offered enough protection for them to be perfect in blustery alpine climbing conditions. I wore them exclusively for all three summits mentioned above and they were perfect even for our 1 AM below freezing alpine starts. A lightweight or mid-weight long underwear pant can easily expand the cold weather capabilities of these though I would pack a hard-shell to zip on over them in extreme cold/windchill/wet conditions.

Comfort- Sizing/Fit

The second best feature of these pants is how well they fit. For reference I am 5′ 9″, 180 pounds, with a 34 inch waist and 32 inch inseam. I went with a size medium and they fit me quite well. They may be an inch long in the inseam but that is only noticeable if I am wearing flip-flops. Once I have trail shoes or boots on they do not feel too long at all and the stretchy material makes rolling them up around the calves for rock climbing super easy. The stretchy material also stays in place around the calf while I am climbing while other pants sometimes un-roll on me mid-pitch if I don’t fuss with a good “tight-roll”. There is also a hem-cord at the ankles that can help keep them tight around your boot or calf with just one pull.

These offer protection in quite a few ways. They are light enough to serve as bug/poison ivy/pricker protection in warm weather. They are durable enough to protect bare legs from rock abrasion while scrambling and climbing. They are virtually wind proof to guard from wind-chill (though I would add a hard-shell pant to my pack if looking at a wind chill advisory). They are water-resistant enough thanks to the DWR coating to deal with light precipitation and when they do get wet they are super quick drying. If glissading on Spring snow is on the agenda I would also add a hard-shell to the kit.

I really like the integrated adjustable web belt and have not had any need to wear an additional belt but low profile belt loops are included anyways. The pant fits great underneath the two harnesses I used with it, the Petzl Sitta (reviewed here) and the Petzl Altitude (review coming). Two zippered hand pockets are perfectly positioned and a zippered right thigh pocket is large enough for my iPhone 6s Plus in its Hitcase Shield waterproof case <- great iPhone case by the way! There is also a zippered right rear pocket to round out the features of this pant.

While I wore these for almost 5 months it was the two weeks that I lived in them in the Cascades that really won me over. Light enough to sleep in yet rugged enough to handle thousands of feet of alpine scrambling. I will likely be wearing these regularly for the rest of the New England Fall climbing season and they will probably go out on some fair weather ice climbing days this winter, though I have a couple heavier soft-shell pants that need to be reviewed this season as well. If you are in need of a versatile climbing pant backed by a great company this model deserves a very close look!

Gear Review: Patagonia Nano Puff® Hoody

A couple months ago I got my hands on the iconic Patagonia Nano Puff® Hoody and I’ve come to discover why I often see climbers milling about both at the cliffs and at the local coffee shop in this well designed piece. The non-hooded version of this jacket won the Editors Choice Classic Award from Climbing Magazine. I prefer hoods on almost all my outdoor clothing so I was happy to review the hooded version. This jacket falls into the “light puffy” category. If you are looking for a full on winter belay jacket you can check out some “full puffy” models I am reviewing here.

So let’s break down what makes this piece an excellent addition to your outdoor wardrobe!


The Patagonia Nano Puff® Hoody uses super light and compressible 60-g PrimaLoft® Gold ECO Insulation. “Gold” Primaloft is the highest level of synthetic insulation and of course being the environmentally conscious company Patagonia is known for they went with the ECO version of Gold which is 55% post-consumer recycled content. So you can feel warm and fuzzy while feeling warm and… ok that’s a bit too cheesy.

The “brick quilting” pattern is superior to other less expensive baffling methods and keeps the insulation in place preventing cold spots.


The Patagonia Nano Puff® Hoody uses 1.4-oz 22-denier 100% recycled polyester with a DWR (durable water repellent) finish. Well what does that mean? 1.4-oz 22-denier feels like silk!

Brick Quilting Pattern = no cold spots

This isn’t a cheap nylon taffeta but a very abrasion resistant and pack-able material. It is quite comfortable over bare skin which is good since I broke this out repeated this Fall to wear directly over a t-shirt.


12.8 oz. / 362 grams. Ultralight weight and super compressible, this is undoubtedly where the jacket go its namesake. Nano in this sense means extremely small. The Patagonia Nano Puff® Hoody easily stuffs into its own internal chest pocket which measures about 8 x 7 x 4 inches.

A lot of warmth in a small little package

A carabiner sewn loop allows you to clip this off to the back of your harness if you are leaving your pack on the ground and the top of the pitch looks a little bit more breezy than the base of the route.


I found the sizing to be spot on. I went with a large which fits my 42 inch chest with a little extra space for a soft-shell and base-layers but not too baggy to throw on over a t-shirt. The hood is sized to fit under your helmet but I found it would fit over as well, but a bit snug.

Probably more comfortable, and warmer, to wear this hood under your helmet unlike traditional belay jackets with over-sized hoods.


Rounding out some of the features I haven’t mentioned yet:

  • Center-front zipper has wicking interior storm flap and zipper garage at chin for next-to-skin comfort
  • Two zippered handwarmer pockets have cleanly finished zipper garages
  • Under-the-helmet hood construction is light and simple
  • Drawcord-adjustable drop-tail hem seals in warmth


This is a super versatile layer that can serve many purposes.

It’s the perfect balance of warmth, weight, and pack-ability for climbing on the edge seasons.

Fall rock climbing is the best rock climbing in the Northeast and this jacket is ideal as your insulating layer all on its own. The DWR finish and warm-when-wet insulation adds protection should you leave the rain shell at home and get surprised by a later afternoon shower. After the leaves have fallen and the ice is starting to grow this becomes an excellent mid-layer, taking the place of heavier and less compress-able 200 weight fleece jackets. With quality long underwear, a soft shell, Patagonia Nano Puff® Hoody, and a hard-shell you have an adjustable system that can handle almost any winter conditions. I’ll still carry a heavier full on belay jacket when swapping leads ice climbing but for fast solo missions this is a perfect companion!
